This allows the PMU LED on both a PowerMac 7,2 (Dual G5 2.0GHz, June 2003)
and a PowerMac 7,3 (Dual G5 2.0GHz, June 2004) to be controlled.
The physical LED is never off, unlike an iBook/PowerBook LED.
It is rather dim ("off") or very bright ("on").

This cleans up how the zImage code manipulates the kernel
command line. Notable improvements from the old handling:
- Command line manipulation is consolidated into a new
prep_cmdline() function, rather than being scattered across start()
and some helper functions
- Less stack space use: we use just a single global command
line buffer, which can be initialized by an external tool as before,
we no longer need another command line sized buffer on the stack.
- Easier to support platforms whose firmware passes a
commandline, but not a device tree. Platform code can now point new
loader_info fields to the firmware's command line, rather than having
to do early manipulation of the /chosen bootargs property which may
then be rewritten again by the core.

This patch adds a library of useful device tree manipulation functions
to the zImage library, for use by platform code. These functions are
based on the hooks already in dt_ops, so they're not dependent on a
particular device tree implementation. This patch also slightly
streamlines the code in main.c using these new functions.
This is a consolidation of my work in this area with Scott Wood's
patches to a very similar end.

There are many adapters which cannot handle DMAing across any 4 GB
boundary. For instance, the latest Emulex adapters.
This normally is not an issue as firmware gives dma-windows under
4gigs. However, some of the new System-P boxes have dma-windows above
4gigs, and this present a problem.
During initialization of the IOMMU tables, the last entry at each 4GB
boundary is marked as used. Thus no mappings can cross the boundary.
If a table ends at a 4GB boundary, the entry is not marked as used.
A boot option to remove this 4GB protection is given w/ protect4gb=off.
This exposes the potential issue for driver and hardware development
purposes.

There are several IOMMU allocator bugs. Instead of trying to fix this
overly complicated code, just mirror the PCI IOMMU arena allocator
which is very stable and well stress tested.
I tried to make the code as identical as possible so we can switch
sun4u PCI and SBUS over to a common piece of IOMMU code. All that
will be need are two callbacks, one to do a full IOMMU flush and one
to do a streaming buffer flush.
This patch gets rid of a lot of hangs and mysterious crashes on SBUS
sparc64 systems, at least for me.

same, the main difference being some keys which may not exist and
leds which might not be present. Therefore it's possible to write
a generic keymap which would allow the use of an unknown keyboard
with little drawbacks. The user can select it specifying the parameter
"keymap=generic".

Acerhk supports already a lot of laptops. Lets import its database so
that everyone can benefit of the work of Olaf Tauber. Only the "tm_new"
laptops were imported. "tm_old" laptops could be possible but requires
more testing and probably only few laptops are still alive. "dritek"
laptops should probably be imported into a different driver. Also compress
the keymaps by fitting each entry on an int. Most of the dmi matching was
written based on google searches, so it's rather prone to errors. That's
why I'm asking people to confirm it works.
Support to generate switch input events was added as some laptops indicate
lid open/close through this interface.

Pete Zaitcev reports that with his touchpad, if he lifts the finger
and places it elsewhere, the pointer sometimes warps dramatically.
This happens because we don't store coordinates unless we detect a
touch so sometimes we have stale coordinates in queue (from where
the finger left the pad) and averaging makes cursor to jump across
